Description

  The present invention relates to a screen display method and a screen display device for displaying a screen, and more particularly to a screen display method and a screen for displaying a screen based on an electronic document and a content object specified in the electronic document. The present invention relates to a display device.

In a mobile phone, a standby screen is displayed during a standby time (that is, a time during which no telephone call or communication is performed). In addition, a function menu screen is also provided for the user to call up the mobile phone functions (phone book function, call function, mail function, WEB function, camera function, various parameter setting functions, etc.). A desired function can be selected. Furthermore, immediately after the mobile phone activates the browser, a WEB menu screen is displayed, and the user can follow the link from this WEB menu screen and access the target WEB page. For example, the initial screen of “Vodafone live!” Described in Non-Patent Document 1 corresponds to the WEB menu screen.
"Vodafone live!" [Searched on November 9, 2005], Internet <URL: http://www.vodafone.jp/japanese/live/index.html>

  The standby screen can usually be customized by the user. For example, a content object of a favorite theme can be downloaded and the content object of the theme can be displayed on the standby screen. it can. You can also select your favorite image as wallpaper. However, the extent to which the user can customize the standby screen is limited. The same applies to the function menu screen. Therefore, in order to enable the user to semi-customize the standby screen and function menu simply, interactively, or potentially completely, for example, the same as the WEB page. In addition, it is conceivable to generate a standby screen or a function menu screen using an electronic document that can be created or edited by a user such as HTML.

  The WEB menu screen is downloaded according to pull distribution. Therefore, when the content object for configuring the WEB menu screen is updated on the WEB server, the mobile phone can display the updated WEB menu screen on the mobile phone. It becomes necessary to newly download a content object for configuring the menu screen. The same applies to a WEB screen provided by a content / object provider or the like on the WEB.

  When the capacity of a WEB page for displaying a standby screen, a function menu screen, a WEB menu screen, or another WEB screen increases, the time for the browser to download and display it increases. In order to solve this, for example, the following technique is used.

  That is, a cache memory is provided on the browser side. Then, the browser stores the WEB page downloaded once from the WEB server in the cache memory in accordance with a request from the user. Thereafter, when the user is requested to display the WEB page again by the user, the browser reads the WEB page from the cache memory and displays it without downloading the WEB page from the WEB server. By doing so, the time required for downloading can be omitted.

  However, in this technique, when the WEB page stored in the cache memory is updated in the WEB server, the browser needs to download the updated WEB page. Therefore, in order to avoid this, the telecommunications carrier and the content object provider cannot update the WEB page frequently.

  In order to enable a browser to download an updated WEB page from a WEB server even when a cache memory is used, for example, the following two types of techniques are used.

  In the first technique, the WEB server transmits the expiration date of the WEB page to the browser together with the WEB page requested by the browser. The browser stores the expiration date and time in the cache memory together with the WEB page. After that, when the user is requested to display the WEB page again, it is determined whether or not the date is before the expiration date. If so, the WEB page is read from the cache memory. , Download the WEB page from the WEB server. According to this technology, even if the WEB page is updated on the WEB server before the expiration date, the browser cannot download the updated WEB page unless the expiration date comes. Therefore, in order to avoid this as much as possible, the operator must set the expiration date to an earlier date. Conversely, even if the WEB page is not updated on the WEB server after the expiration date has passed, when the user is requested to display the WEB page again after the expiration date has passed, the browser downloads the same WEB page. It will be. Therefore, the operator cannot excessively set the invalid date / time to an early date / time in order to suppress useless communication.

  In the second technique, the WEB server transmits a WEB page to the browser, but does not transmit the expiration date of the WEB page to the browser. The browser stores the downloaded WEB page in the cache memory, obtains the date and time (download date and time) when the WEB page was downloaded from the internal clock, and stores it in the cache memory and the like. Thereafter, when the user is requested to display the WEB page again, the browser requests the WEB server to transmit the WEB page, but adds a download date and a revocation confirmation request to the request. The WEB server holds the date (update date) when the WEB page is updated and becomes the current one, and compares the download date with the update date. If the download date and time is after the update date and time, the WEB page stored in the cache memory on the browser side is the latest, so the WEB server only sends a message “valid” to the browser. . On the other hand, if the download date is earlier than the update date, the WEB page stored in the browser cache memory is old, and the WEB server transmits the latest WEB page to the browser. This second technique does not have the problems of the first technique described above. However, the calculation amount of the terminal and the communication session between the terminal and the WEB server increase, and as a result, the time until the WEB page is displayed becomes long.

  Further, in order for each user to customize the layout of the WEB page and the type of content object to be posted on the WEB page according to his / her preference, the WEB server side creates such a WEB page for each user. Must be processed for. If electronic documents and content objects for configuring customized WEB pages are individually provided to tens of millions of users, the amount of processing and the amount of communication will be enormous.

  Therefore, the present invention provides a screen display method capable of displaying a screen that can be customized for each user without imposing a heavy load on the server and the communication line and with a short waiting time for the user. An object is to provide a screen display device.

Therefore, storing the push type content object in a predetermined area and inputting an electronic document (including input by downloading) Therefore, it is possible to store individual push-type content objects in a predetermined area and input electronic documents (including input by downloading) at different times. It becomes. Accordingly, it is possible to appropriately set each storage time or input time in consideration of the capacity of the push-type content object, the load on the server, the load on the communication line, and the like.

  The best mode for carrying out the present invention will be described below in detail with reference to the drawings.

  In the present embodiment, the terminal generates a screen by using an electronic document and a content object described to display the screen on the electronic document, and displays the screen. The terminal is a mobile phone, a personal computer, a PDA (Personal Digital Assistant) or the like. The electronic document is a document described in a markup language such as an HTML document. The content object is a still image, a moving image, text, or the like. An electronic document is also a type of content object, and in the following description, an electronic document is explicitly described unless the electronic document is explicitly excluded or distinguished from other content objects. Even if not, the content object includes an electronic document. A CSS (Cascading Style Sheet) describing a layout or the like is also a type of content object. The content object may output audio, but is omitted in the following description unless otherwise specified.

[Content Object]
A folder for storing content objects for configuring the screen (hereinafter referred to as “content object folder”) is provided in a memory in the terminal or a memory connected to the terminal. Then, the push type content object downloaded according to the push type distribution is stored in the content object folder. The content object folder may store a pull-type content object downloaded according to pull-type distribution, or may store a non-download type content object input by a method other than downloading.

  Downloading according to push-type distribution refers to downloading that is performed according to an opportunity caused by the server. Here, the server is, for example, a management server described later.

Downloading according to pull-type distribution refers to downloading performed in accordance with a trigger that the terminal has caused.
Non-downloadable content objects are input from, for example, still image files or video files captured by the camera built into the terminal, audio files recorded by the microphone built into the terminal, or a memory card inserted into the terminal Content objects, content objects input from other devices connected to the terminal, and the like.

[Content object folder]
The terminal determines the correspondence between the directory information indicating the location of the content object folder and a predetermined name for indicating the content object folder (hereinafter referred to as “content object folder name”). Hold it in memory etc. As a result, the content object in the content object folder can be specified by the set of the content object folder name and the content object identification information (for example, the file name). The content object folder name may be a description of only the protocol name for accessing the content object folder, such as “vf: //”. For example, if “vf: //idle.htm” is designated, the WEB browser installed in the terminal reads an HTML document named “idle.htm” in the content object folder, and “vf If ": //wallpaper.jpg" is specified, the jpeg file named "wallpaper.jpg" in the content object is read. A program that accesses a content object in the content object folder can also correctly recognize the content object folder with reference to this correspondence.

  In addition, the correspondence between the directory information indicating the location of the content object folder and the predetermined name for indicating the content object folder is common to all terminals of the same carrier. To do. By doing this, even if the root folder is different for different manufacturers and different models, all terminals of the same carrier can correctly recognize the content, object, and folder. It becomes.

  Also, by copying or moving a content object stored in a folder other than the content object folder or the root directory to the content object folder, the content object folder name and the content object file name can be changed. The set makes it possible to access the content object. In addition, a utility for copying or moving a content object in a folder specified by the user to the content object folder is installed in the terminal, and the content object folder is not specified as the copy destination or movement destination. Alternatively, it may be possible to copy or move by simply designating the folder containing the content object to be copied or moved and the content object. Then, there is no mistake in the copy destination or move destination.

[Download method and timing]
The terminal downloads the content object to be included in the display screen asynchronously with the electronic document that is the framework of the display screen. In particular, the terminal may download the content object included in the display screen before downloading the electronic document that is the framework of the display screen. For example, the management server knows which terminal should download which electronic document and which content object, and has recognized that an electronic document or a certain content object has been updated on the server. Then, a short message including information (URL or the like) for the terminal to download the updated electronic document or the updated content object from the content server is transmitted to the corresponding terminal. The terminal that has received the short message downloads an electronic document or content object from the content server in accordance with the information contained therein. This is a download according to push distribution when viewed as a whole. In addition, the management server does not perform the transmission of the short message immediately after grasping the update of the content object or the like, but after grasping, it is estimated that the traffic of the line is less than the predetermined value, or It may be performed after waiting until the detected time zone (for example, at night or early morning). By doing so, it is possible to download a large-capacity content object to the terminal without squeezing the communication line. Further, the terminal may perform the download when it enters a standby state for the first time after receiving the short message, rather than immediately after receiving the short message. Therefore, it is estimated that the communication amount of the line is less than a predetermined value, or the download may be performed only during the time when the terminal in the detected time zone is in a standby state.

  Also, the electronic document and each content object constituting one display screen are generally updated individually. Therefore, the download is performed individually, and the download time is also different. Thus, for example, if a content object representing news is frequently updated on the server, the content object is frequently downloaded alone.

[Method from download to display]
In accordance with the instruction from the management server, the push proxy gateway transmits the URL of the content object to be inserted into the display screen to the terminal using, for example, a short message. A download agent is installed in the terminal, and the download agent downloads the content object from the content object server according to the URL. The downloaded content object is stored in the content object folder via the digital light management unit. As described above, the content object stored in the content object folder in this way is a combination of the content object folder name and the file name of the content object (for example, “vf: //wallapper.jpg”). ). This set is described in the electronic document, and the browser reads the content object from the content object folder according to the description.

  When a content object is specified (by URL) in accordance with a conventional description method in the electronic document, the browser downloads the content object from the WEB server according to the URL. Therefore, by specifying the content object stored in the content object folder not only by the file name of the content object but also by the set of the content object folder name and the content object file name, the browser It becomes possible to distinguish between the content object stored in the content object folder and the content object stored in the WEB server. Note that when the content object is specified only by the file name of the content object, it is interpreted that the position of the content object is specified by the relative address. For example, if both an electronic document and a content object are stored in the content object folder and only the file name of the content object is described in the electronic document, the content stored in the content object folder -The object will be accessed.

[Stand-by screen and function menu screen (content type and dyne loading timing)]
In the case of the standby screen, it is necessary to be able to display the latest screen even when the terminal is out of service area. Therefore, it is necessary to update the electronic document or content object for composing the standby screen with the screen display start request as a trigger. Considering the case in the environment, it is not preferable. Therefore, it is possible to update the electronic document and the content object included in the screen display screen before the screen display start request is issued. In other words, the electronic document and the content object for configuring the standby screen must be set as push-type content so that the terminal can download them at an early stage. However, downloading according to push-type distribution of content objects with low update frequency is sufficient if it is performed at a time when the traffic is low, such as at night or early morning. Also, in order not to squeeze the communication line, it is necessary to download a large-capacity content object according to the push-type distribution at a time when the communication amount is small, such as at night or early morning. On the other hand, downloading according to push-type distribution of news and weather forecast content objects to be displayed on the standby screen needs to be performed frequently, and since the capacity of such content objects is small, this download is Do it frequently.

  The content objects that make up the function menu screen and the download timing thereof are the same as the standby screen.

  In an electronic document that is a framework of a standby screen, a set of a content object, a folder name, and a still image file name is described as information for specifying a still image used as a wallpaper of the standby screen. Therefore, by copying or moving the still image file that the user wants to use as wallpaper to the content object folder and setting the file name of the still image file as the file name described in the electronic document, The wallpaper that the user wishes to use can be displayed on the screen. However, a still image file to be used as wallpaper is stored in an arbitrary folder with an arbitrary file name. Therefore, it is possible to install a wallpaper setting utility on the terminal, do not specify the content object folder as the copy destination or move destination, and do not specify the still image file name in the content object folder. By simply specifying the folder containing the still image file to be copied or moved and the still image file, copying or moving the still image file to the content object folder and a predetermined file name (for example, You may be able to change to "wallpaler.jpg"). By doing so, there is no mistake in the copy destination or movement destination, and there is no mistake in the name of the still image file for wallpaper. The source still image file may be obtained from an arbitrary location (for example, a camera or a server of a content object provider), stored in an arbitrary folder, and given an arbitrary file name. By copying or moving and changing the file name, such a still image file can be used as a still image file for wallpaper by a utility or the like.

[WEB menu screen (content type and dyne load timing)]
The content object constituting the WEB new screen and the download timing thereof may be the same as the standby screen. In particular, in order to shorten the waiting time from when the user performs an operation for displaying the WEB menu screen to when the latest WEB menu screen is displayed, the push is performed as a content object constituting the WEB menu screen. A content object according to type distribution may be used.

  However, when the user tries to access various WEB pages, considering that the WEB menu screen is displayed first, the latest WEB menu screen can be displayed correctly only when the terminal is within range. Good. Therefore, the content object according to the pull-type distribution may be used as the content object constituting the WEB menu screen. However, even in this case, as a content object having a large capacity among the content objects constituting the WEB menu screen, the content object according to the push type distribution is used, and the traffic volume at night or early morning is used. The download may be performed in a short period of time to avoid pressure on the communication line. On the contrary, since the electronic document constituting the framework among the content objects constituting the WEB menu screen has a small capacity, the content object conforming to the pull-type distribution is always used as the electronic document. Good.

  When downloading in accordance with pull-type distribution, a folder (which may be a content object folder or another folder) in which a pull-type content object is stored may be a background art. Whether or not it is necessary to re-download the content object by any one of the two methods of the cache memory update described in the background art, assuming that it is the cache memory described in the column The content object may be downloaded when it is determined that it is necessary.

  Since the capacity of the electronic document for configuring the WEB menu screen is small, the timing for downloading the electronic document according to the pull-type distribution may be when the user requests the display of the WEB menu screen.

  On the other hand, for content objects having a large capacity among the content objects for configuring the WEB menu screen, this content object is downloaded according to pull distribution at night or early in the morning so as not to compress the communication line. It is preferable.

  Downloading of content objects according to such pull-type distribution may be performed by controlling the WEB browser from other parts of the terminal, or may be performed according to a script described in the electronic document.

  For example, the terminal continuously determines whether or not a content object needs to be downloaded during idle time, and if necessary, downloads the content object during idle time and stores it in the terminal folder. Content objects can always be kept up to date.

  In this way, downloading content objects during idle time eliminates the need to download content objects when the display screen is requested, reducing the time from request to display. can do.

  As a download method according to pull-type distribution, the terminal transmits a download request to the management server described above, the management server sends a short message according to the request, and the terminal is described in the short message. A method of downloading a content object according to information such as a URL may be used. At this time, for example, when the load state of the content server or the communication line is heavy, the management server may stop or postpone the transmission of the short message.

[effect]
In the prior art method, when it is determined that the updated display screen needs to be downloaded, all of the electronic documents included in the display screen and the display screen are included in accordance with the display screen download request from the terminal. Since the content object must be downloaded from the server to the terminal in a short time, the instantaneous load of the server, the instantaneous load of the terminal, and the instantaneous communication amount of the communication path increase. When a request for downloading the display screen is issued from a large number of terminals all at once, the server may not function due to overload, and the communication path may be congested.

  On the other hand, in this embodiment, whether to follow push-type delivery or pull-type delivery, instead of determining whether or not an updated display screen needs to be downloaded, update The determination of whether or not the downloaded individual content object is necessary and the determination of whether or not the updated electronic document needs to be downloaded are performed separately. The former judgment is made sparsely during idle time. The latter determination may be performed sparsely during idle time, or may be performed when a display screen is requested by a user or the like. Therefore, it is not necessary to download all the content objects included in the display screen from the server to the terminal in a short time, so that the instantaneous load of the server, the instantaneous load of the terminal, and the instantaneous communication volume of the communication path are avoided. be able to. Further, the time from the screen display request to the screen display can be shortened.

[System configuration]
FIG. 1 is a block diagram showing a configuration of a screen display system according to an embodiment of the present invention.

  Referring to FIG. 1, the screen display system according to the present invention includes a push type content object server 101, a management server 102, a push proxy gateway 103, a pull type content object server 105, and a terminal 107.

  The push-type content object server 101 stores various push-type content objects and causes the terminal 107 to download the push-type content object requested from the terminal 107.

  The push proxy gateway 103 transmits a short message to the terminal 107 as a trigger for the terminal 107 to download the push type content object from the content object server 101. This short message includes the URL of the content object.

  The management server 102 monitors the update of the push type content object in the push type content object server 101. Further, the push type content object server 101 may detect an update of the push type content object and notify the management server 102 of the update. The management server 102 may simultaneously update the push type content object and send the short message.

  In addition, the management server 102 stores data representing information as to which terminal 107 the updated push type content object is used. This data is created at the time of designing the screen of each terminal 107, for example. Therefore, if a push-type content object is updated, a short message for downloading it is transmitted to all the terminals 107 that use it.

  Since the push-type content object server 101 transmits a content object to the terminal 107 triggered by a short message transmitted from the push proxy gateway 103 to the terminal 107, this sequence is viewed as a whole. In this sense, the content object transmitted in this way is a push type content object as described above.

  In addition, the delivery of the push-type content object triggered by the short message is that the destination of the short message is the mobile phone number, so that each terminal 107 can be designated as the delivery destination. Because. Therefore, for example, if individual terminals 107 can be specified by other types of telephone numbers, IPv6 IP addresses, MAC addresses, e-mail addresses, etc., the push type content object is triggered by a message addressed to these terminals. Distribution may be started. Further, the push type content object server 101 may voluntarily distribute the push type content object to the terminal 107 using information that can identify the terminal 107 without using an auxiliary means such as a short message. .

  The push proxy gateway 103 transmits a short message to the terminal 107 when the terminal 107 first constructs a predetermined screen (for example, a standby screen), for example. For this purpose, for example, the push proxy gateway 103 receives a request for transmission from the management server 102.

  The short message includes information for downloading all the push-type content objects included in a predetermined screen in a single or a plurality. Information for downloading all the push-type content objects included in a predetermined screen may be included in one short message. Information for downloading a part of push-type content objects included in a predetermined screen (for example, content objects belonging to a certain theme) is included in one short message, and a plurality of short messages are included. A message may cover all push-type content objects included in a predetermined screen. Information for downloading individual push type content objects included in a predetermined screen is included in one short message, and all the push type content objects included in the predetermined screen are displayed by a plurality of short messages. You may make it cover. However, even if one push-type content object is associated with one short message or a plurality of push-type content objects are associated with one short message, one short message has one push-type content object. One URL including the domain name of the content object server 101 is made to correspond. Then, one push type content object or a plurality of push type content objects organized in a multipart format is associated with the URL.

  The push proxy gateway 103 is used to cause the terminal 107 to download the push type content object when at least a part of the push type content object for constructing a certain screen of the terminal 107 is updated. A short message is transmitted to the terminal 107. For this purpose, the management server 102 grasps the update of the push type content object.

  Further, the terminal 107 may request the management server 102 to cause a short message to be transmitted in response to this request. However, in order to prevent the short message from being congested, the management server 102 needs to provide a filter for permitting / prohibiting or adjusting the time for the request from the terminal 107.

  The pull-type content object server 105 stores various pull-type content objects and causes the terminal 107 to download the pull-type content object requested from the terminal 107. The various pull-type content objects are, for example, electronic documents, still images, moving images, sounds, CSS (Cascading Style Sheets), characters, and the like constituting the screen framework, as with the push-type content objects. These are also used in the terminal 107 to construct a screen (for example, a normal WEB screen).

  In FIG. 1, one push type content object server 101 and one pull type content object server 105 are shown, but there may be a plurality of these. The at least one pull-type content object server 105 is a server for providing an electronic document that serves as a framework for the WEB menu screen. This server is typically provided by a communication carrier. . The pull-type content object server 105 may be a general WEB server.

  The content object folder 121 stores various push type content objects, various pull type content objects, and various non-download type content objects.

  The content object folder 121 is basically provided in a recording medium (flash memory or the like) built in the terminal 107, but may be provided in a recording medium connected to the terminal 107. Further, it may be provided in an arbitrary directory or sub-directory in the file system.

  However, in order to access the content object folder 121, a header common to a plurality of terminals is used. The common range is, for example, a range including all terminals contracted with one communication carrier, even if it is narrow. Accordingly, it is necessary to set information for associating the location information (for example, directory information) of the content object folder 121 with the header in each terminal. It is set at the time of contract with the user and does not need to be set by the user.

  The header is, for example, protocol identification information “vf: //”, and the browser distinguishes it from standard protocol identification information such as “http: //”, “ftp: //”, “file: //”. Keep it attached. When “files: //” is used, the browser can access a local (in the terminal 107) file, but the root directory differs depending on the operating system. In other words, in a certain operating system, a directory directly under the operating system is treated as a root directory, and in another certain operating system, a user directory is treated as a root directory. Therefore, for example, even if “files: //index.htm” is specified, it is not always possible to access an assumed electronic document. On the other hand, in this embodiment, in the common range, information for associating the location information (for example, directory information) of the content object folder 121 and the header is set in each terminal. If the object name (for example, “vf: //index.htm”) is specified, the electronic document index.htm in the content object folder 121 can be accessed without fail.

  Further, a push type content object download unit 125, a pull type content object download unit 133, and a non-download type content object input unit 137, which will be described later, are also used for associating the location information of the content object folder 121 with the header. Using the information, the content object of the content object folder 121 can be accessed by the header and the content object name. For example, if the electronic document index.htm is to be stored in the content object folder 121, “vf: //index.htm” may be specified.

  Further, a sub-folder may be provided under the content object folder 121 so that the content object in the sub-folder can be designated by a relative designation method based on the content object folder 121. . For example, “vf: //sub1/index.htm” is used to access the electronic document index.htm in the sub folder sub1 immediately below the content object folder 121.

  In addition, a plurality of sub folders are provided under the content object folder 121, and further, which sub folder is to be used is determined by user designation or the like, and the sub folder is the content object folder. You may treat it as 121. For example, when subfolder sub1 and subfolder sub2 are provided immediately below content object folder 121 and subfolder sub1 is selected and “vf: //index.htm” is specified, Actually, “vf: //sub1/index.htm” may be accessed. For example, a plurality of sub-folders are provided for each theme, a common content object name is given to the same element in the page, and a sub-folder corresponding to a favorite theme is designated every time. Here, the theme is selected from, for example, a plurality of animation characters and motifs (Japanese style, Western style, natural tone, etc.) prepared in advance. In this way, it is not necessary to specify a sub-folder for each individual content object in the favorite theme.

  Further, when the content object is read from the content object folder 121, the name of the content object is only the name of the main body (that is, without an extension). In this order, a content object with the same body name may be searched for, and the first found content object may be read out. For example, the order of extensions specified in advance is set as `` bmp '' → `` jpg '' → `` gif '', and when `` wallpaper '' is specified, `` wallpaper.bmp '' → `` wallpaper.jpg '' → `` wallpaper. The content object may be searched in the order of “gif”, and when “wallpaper.jpg” is first found, it may be read and the still image may be restored by a decoder corresponding thereto. In this way, for example, the format of a still image that is desired to be used as a wallpaper for the standby screen can be freely selected from a predetermined range. Further, this priority may be specified by the user. Of course, a specific extension may be specified. These priorities and extensions may be specified, for example, in the course of the user designing the standby screen WEB page interactively.

  Further, when referring to a content object in the content object folder 121 from an electronic document in the content object folder 121, a relative designation method can be used without adding a header. For example, when referring to the still image content object fish.jpg in the subfolder sub1 under the content object folder 121 from the electronic document index.htm in the content object folder 121, “sub1 / fish.jpg Can be specified.

  The WAP receiving unit 123 receives the short message, performs processing related to the WAP, and pushes information (such as the URL of the push type content object) necessary for downloading the push type content object in the short message. The content is output to the type content object download unit 125.

  The push type content object download unit 125 downloads the push type content object from the push type content object server 101 based on the information input from the WAP reception unit 123 and stores it in the content object folder 121. . The push type content object download unit 125 may perform the download immediately after inputting the information for downloading the push type content object from the WAP reception unit 123. For example, until the load on the terminal 107 decreases, The download may be suspended until the communication amount of the terminal 107 decreases, until the radio wave condition is improved, or until a plurality of predetermined conditions are met.

  The user interface 127 includes a key group, a display unit, a microphone, a speaker, and a control unit that controls them. The user interface 127 transmits input and requests from the user to each unit of the terminal 107, and outputs information from each unit. To do.

  The browser 129 generates image data for displaying the screen on the display unit based on the electronic document corresponding to the screen requested by the user and the content object linked to the electronic document, and outputs the image data to the display unit. If the content object of the audio file is linked from the electronic document, an audio signal is output to the speaker.

  The browser 129 can display a WEB screen based on the electronic document read from the content object folder 121, or can display the WEB screen based on the electronic document downloaded from the pull-type content object server 105. You can also It is also possible to temporarily store the electronic document downloaded from the pull-type content object server 105 in the cache memory 131, read it from here, and display the WEB screen based on this. When the cache memory 131 is used, an update method as described in the background art section may be used.

  In addition, the browser 129 determines whether the content object stored in the content object folder 121 is described in the electronic document regardless of where the electronic document is input. Access the content object stored in. The same applies to content objects to be stored in the content object folder 121. Also, the browser 129 determines that the pull type content object stored in the pull type content object server 105 is described in the electronic document regardless of where the electronic document is input. A pull-type content object is downloaded from the content object server 105. Similarly to the browser 129, the plug-in on the browser 129 can freely switch the access destination of the content object according to the description.

  If a script for downloading an updated version of the push type content object stored in the content object folder 121 from the push type content server 101 is described in the electronic document, the push is performed according to the description. An updated version of the type content object is downloaded from the push type content server 101. Similarly, when a script for downloading an updated version of the push type content object stored in the content object folder 121 from the pull type content server 105 is described in the electronic document, according to the description, An updated version of the push type content object is downloaded from the pull type content server 105. In such a case, the content object has both a push type and a pull type property.

  The operation of the above paragraph is the same for the content object first stored in the content object folder 121 as a pull-type content object or a non-download type content object.

  The cache memory 131 is used by the browser 129 and is similar to the browser cache memory in the prior art. That is, the browser 129 temporarily stores the pull-type content object in the cache memory 131 or updates it in the same manner as a normal browser.

  The pull-type content object download unit 133 downloads the pull-type content object from the pull-type content object server 105 and stores it in the content object folder 121. The pull-type content object download unit 133 performs such a case when, for example, the user requests download of the pull-type content object via the user interface 127.

  The digital copyright management unit 135 performs processing for copyright management on the push-type content object that requires copyright management and the pull-type content object that requires copyright management. To do. This processing is, for example, billing processing or processing for authorizing the use of a predetermined range, and is performed in cooperation with a digital copyright management server (not shown). The processing for permitting the use of a predetermined range includes, for example, decryption of a content object using a decryption key, permission / prohibition processing of decryption when a use is requested, and re-encryption of a decrypted content object. Storage, etc.

  The non-download type content object input unit 137 stores the non-download type content object in the content object folder 121.

[Download according to push distribution]
Next, a method of downloading the push type content object by the push type distribution method will be described with reference to FIG.

  First, the push proxy gateway 103 transmits a short message to the WAP reception unit 123 (step S201).

  Next, the WAP reception processing unit 123 performs processing related to WAP on the short message transmitted in step S201 as described above, and downloads the push-type content object in the short message. Necessary information (such as the URL of the push type content object) is output to the push type content object download unit 123 (step S203).

  Next, the push type content object download unit 125 transmits a push type content object transmission request to the push type content object server 101 based on the information input from the WAP reception unit 123 (step S205). ).

  In response to this, the push-type content object server 101 transmits the requested push-type content object to the push-type content object download unit 125 (step S207).

  Next, the push type content object download unit 125 stores the push type content object transmitted in step S207 in the content object folder 121 (step S209). The designation as to whether the push-type content object is stored directly under the content object folder 121 or in any sub-folder under the content object folder 121 is included in the short message. It may also be specified by the user.

  Next, if the downloaded push-type content object requires digital copyright management, the push-type content object download unit 125 confirms that the storage of the push-type content object has been completed. The copyright management unit 135 is notified (step S211).

  In response to this, the digital copyright management unit 135 performs processing necessary for the initial stage of digital copyright management processing (for example, terminal-side processing of billing processing, downloading of a decryption key, use permission) Range information download etc.) (step S213).

  However, when the push-type content object download unit 125 completes the reception of the push-type content object transmitted in step S207, the push-type content object download unit 125 notifies the digital rights management unit 135 that the reception has been completed, and responds accordingly. Then, the digital copyright management unit 135 may perform step S213 and then store the push type content object in step S211.

[Download according to pull type distribution]
Next, a method of downloading the pull type content object by the pull type distribution method will be described with reference to FIG.

  The pull-type content object download unit 133 transmits a pull-type content object transmission request to the pull-type content object server 105 (step S221).

  In response to this, the pull type content object server 105 transmits the requested pull type content object to the pull type content object download unit 133 (step S223).

  Next, the pull-type content object download unit 133 stores the pull-type content object transmitted in step S223 in the content object folder 121 (step S225). The designation as to whether the pull-type content object is stored directly under the content object folder 121 or in any subfolder under the content object folder 121 is included in the short message. It may also be specified by the user. Further, step S225 need not be performed. Further, the pull-type content object may be stored in the cache memory 131 without performing step S225.

  Next, when the downloaded pull-type content object requires digital copyright management, the pull-type content object download unit 133 indicates that the storage of the pull-type content object has been completed. The copyright management unit 135 is notified (step S227).

  In response to this, the digital copyright management unit 135 performs processing necessary for the initial stage of digital copyright management processing (for example, terminal-side processing of billing processing, downloading of a decryption key, use permission) Download range information) (step S229).

  However, when the pull-type content object download unit 133 completes the reception of the pull-type content object transmitted in step S223, the pull-type content object download unit 133 notifies the digital copyright management unit 135 of the completion of the reception, and accordingly Then, the digital copyright management unit 135 may perform step S229, and then store the pull type content object in step S227.

  Note that the browser 129 also downloads the pull-type content object from the pull-type content object server 105 as necessary, similarly to the pull-type content object download unit 133. Normally, the pull-type content object downloaded by the browser 129 is not stored in the content object folder 121, but may be stored. In order to store the pull-type content object downloaded by the browser 129 in the content object folder 121, for example, a script for that purpose is described in an electronic document. Further, when the pull-type content object is not stored in the content object folder 121, it may be stored in the cache memory 131.

[Details of stand-by display]
Next, the standby screen displayed on the display unit of the terminal 107 will be described.

  In this embodiment, a standby screen is generated by the browser 129 and displayed on the display unit. Further, it is usually necessary to display the radio wave state and the remaining battery level on the standby screen. Also, it is convenient to display a digital clock or analog clock, weather forecast, or breaking news on the standby screen. Further, it is convenient to display objects (characters or icons) linked to the favorite display screen on the standby screen. For these displays, the browser 129 inputs an electronic document and a content object linked to it. The arrangement of these objects is specified by CSS. That is, the radio wave state, remaining battery level, wallpaper, digital clock or analog clock, weather forecast, breaking news, CSS, link objects to favorite display screens, and the like are displayed by corresponding content objects.

  For example, the radio wave state is displayed by inputting a signal representing the radio wave state from a function unit (not shown) that detects the radio wave state, and based on this, a script (contents) for displaying a graphic corresponding to the radio wave state・ This is a kind of object.) This script may be provided as a push-type content object.

  In addition, the battery remaining amount is displayed by inputting a signal representing the remaining battery amount from a function unit (not shown) for detecting the remaining battery amount, and displaying a figure corresponding to the remaining battery amount based on this signal. This script (a type of content object) is used. This script may be provided as a push-type content object.

  Further, for displaying the wallpaper, a still image file (a type of content object) and a moving image file (a type of content object) are used. This still image file or moving image file may be provided as a push-type content object.

  A digital clock or analog clock is displayed by a script (content object) for inputting a signal representing the current time from a clock unit (not shown) and displaying a figure or a numerical value corresponding to the current time based on the signal. 1). This script may be provided as a push-type content object.

  The weather forecast is displayed by a script (a type of content object) for downloading weather forecast information from a weather forecast distribution server (not shown) and displaying a graphic corresponding to the weather forecast information. Weather forecast information is also a type of content object. Further, a graphic representing the contents of the weather forecast may be downloaded from the weather forecast distribution server and displayed. A graphic representing the weather forecast information and the content of the weather forecast may be provided as a push-type content object.

  The news bulletin is displayed by a script (a kind of content object) for downloading news information from a news distribution server (not shown) and displaying characters representing the news information. Note that news information is also a type of content object. This news information may be provided as a push-type content object.

  Further, SVG (Scalable Vector Graphics) data including a news character string may be used as a push-type content object representing news information.

  The display of the link object on the favorite display screen is an electronic document including an URL of the display screen and an object linked to the URL (an electronic document called from an electronic document for forming a framework of the entire standby screen, This is a type of content object.) This electronic document may be provided as a push-type content object. For this purpose, as preparation, information related to favorites is sent from the terminal to the server in an interactive format, the electronic document is generated by the server, and the electronic document is stored in the push-type content object server 101. Further, an application program for generating this electronic document based on the information about the favorite input from the user and storing the electronic document in the content object folder 121 as a non-download type content object is stored in the terminal 107. It may be provided.

  CSS realizes a standby screen layout designed in an interactive format, and may also be provided as a push-type content object.

  In the present embodiment, the content object for configuring the standby screen may be any of a push type content object, a pull type content object, and a non-download type content object.

  However, basically, the push-type content object is used as a content object constituting the standby screen and is stored in the content object folder 121. In any terminal 107, the same name (for example, “vf: //idle.htm”) is given to the browser 129 as the name of the electronic document for forming the framework of the entire standby screen. In the electronic document, a content object in the content object folder 121 is described as a content object in order to obtain a display portion included in the standby screen. For example, in the electronic document, the file name “vf: //rfstrength.js” of the script is described as the name of the content object in order to obtain the radio wave state display part included in the standby screen. Here, “js” is an extension of JavaScript (“Java” is a registered trademark), but the script may be in another language.

  In this way, even if the electronic document for forming the framework of the entire standby screen is any of the push type content object, the pull type content object, and the non-download type content object, the content object If stored in the folder 121 under the name “idle.htm”, the browser 129 can display a standby screen based on the electronic document.

  In addition, for example, in order to obtain a radio wave state display part included in the standby screen, the content object may be any of a push type content object, a pull type content object, and a non-download type content object. If stored in the object folder 121 with the name “rfstrength.js”, the browser 129 can display the radio wave state display part based on the content object.

  For example, the terminal 107 can be purchased by storing the content object folder 121 in a content object (including an electronic document) necessary for the browser 129 to display a basic standby screen in the content object folder 121 when shipped from the factory. The user who has done this can immediately view the standby screen.

  If the store of the terminal 107 requests the management server 102 to transmit a short message by a simple operation by a store clerk or the like, then the content object is obtained by the download method by push distribution described with reference to FIG. A content object (including an electronic document) necessary for the browser 129 to display a basic standby screen is stored in the folder 121, and the user who purchased the terminal 107 immediately sees the standby screen. Can do.

  Further, the user may not be tired of the basic standby screen and may want to customize the standby screen. In order to meet such a demand, an interactive display screen (such as a display screen including a form for transmitting information input by the user to the server) provided by the management server 102 or a server linked with the management server 102 is displayed. Information for customizing the standby screen (standby screen customization information) can be transmitted to the management server 102 by the terminal 107 or a personal computer. Based on the standby screen customization information, the management server 102 selects a push-type content object necessary for configuring the customized standby screen. Thereafter, in response to an instruction from the management server 102, short messages regarding these necessary push-type content objects are sent. Then, the push-type content object (electronic document) necessary for the browser 129 to display the standby screen customized in the content object folder 121 by the download method by push distribution described with reference to FIG. Is stored). Thereafter, the user can view the customized standby screen.

  For example, the customization is performed by combining richness, layout, and theme. Here, the richness is a degree of use of a large-capacity content object (for example, an image content object). That is, a standby screen in which images are used everywhere is a standby screen with a high degree of richness, and conversely, a standby screen in which little or no images are used is a standby screen with a low richness. The layout is realized by combining the positions, sizes, and ranges of individual character strings and images with respect to a plurality of character strings and images. The theme is as described above.

  Also, for example, a large number of standby screens customized in advance may be prepared so that the user can select them. In addition, a list of contents / objects that can be displayed on the standby screen is displayed on the interactive customization display screen (such as a display screen including a form) provided by the management server 102 or a server linked with the management server 102, and is selected by the user. Only the contents / objects that have been selected may be displayed on the standby screen. The customized screen layout and the like are described by CSS which is a content object.

  Further, the user may want to change only some of the content objects (for example, wallpaper) in the standby screen. In order to respond to such a request, an image file that the user wants to use as wallpaper may be stored in the content object folder 121 by the non-download type content object input unit 137. Alternatively, the image file that the user wants to use as wallpaper may be downloaded from the pull-type content object server 105 by the pull-type content object download unit 133 and stored in the content object folder 121. In these cases, in the electronic document, at least the main part of the name of the content object to be used as the wallpaper is determined. Therefore, the non-download type content object input unit 137 and the pull type content object download unit 133 are used. Changes at least the main part of the name of the image file to the determined one.

  Further, an image file that the user wants to use as wallpaper may be downloaded from the push type content object server 101 by the push type content object download unit 125 and stored in the content object folder 121. For this purpose, the user can select a favorite wallpaper from a plurality of prepared wallpapers on an interactive display screen (such as a display screen including a form) provided by the management server 102 or a server linked thereto. Thus, information for specifying this (wallpaper specifying information) can be transmitted to the management server by the terminal 107 or a personal computer. Thereafter, in response to an instruction from the management server 102, a short message regarding the image file selected by the user is sent. Then, the image file selected by the user is stored in the content object folder 121 by the download method by push distribution described with reference to FIG. Thereafter, the image file selected by the user is displayed on the standby screen.

  Also, certain types of content objects may be updated. For example, weather forecast information and news information are updated at regular intervals. In addition, a script for performing a certain display may be upgraded. In order to automatically reflect such an update of the content object on the terminal 107, such a content object is set as a push type content object, and the management server 102 that recognizes the update of the push type content object , Requesting push proxy gateway 103 to send a short message to those terminals 107 in order to have all terminals 107 that contain the content object in the standby screen download the push-type content object To do.

  Further, the push type content object downloaded from the push type content object server 101 is updated by periodically downloading from the push type content object server 101 or the pull type content object server 105 thereafter. It is also possible to embed a script for use in an electronic document constituting the entire standby screen, or to call such a script as a content object from an electronic document constituting the entire standby screen. Since the terminal 107 is in the standby state for most of the time, the browser 129 executes the content object of the standby screen for most of the time. Therefore, the update script can be downloaded from the push type content object server 101 or the pull type content object server 105 and updated without a short message.

  When a certain theme is selected, an image group belonging to the theme is used on the standby screen. Such an image group is downloaded from the push-type content object server 101 to the terminal 107 in a multipart format, and is divided into individual images by the terminal and then stored in the content object folder 121.

  In addition, the user does not always select the same theme, and it is assumed that the user changes the theme. In order to cope with this, an image group of a new theme can be downloaded from the push type content object server 101 to the terminal 107 as in the case of initially customizing the standby screen. On the other hand, if only the theme is changed, the other content objects for configuring the standby screen are not changed, and only the image group is changed. Therefore, the image itself used at each place on the standby screen is different before and after the update, but the file name of the image is the same. It is possible to cope with this by simply overwriting an image group of an existing theme with an image group of a new theme. But this is not user friendly. Therefore, a plurality of sub folders for each theme are provided under the content object folder 121, and an image group of each theme is stored in the corresponding sub folder. Then, the user can select which theme to use, and the image group is read from the sub-folder corresponding to the selected theme.

  For this purpose, for example, not only a group of images different for each theme but also a content object common to all themes is stored in a sub-folder. Then, if the electronic document that constitutes the entire standby screen of the selected sub-folder is read, particularly without additional processing to recognize the position of the linked content object, The standby screen corresponding to the selected theme can be displayed. Or, only a group of images different for each theme is stored in the sub-folder. In this case, the browser 129 is made to recognize the sub folder corresponding to the selected theme, and the group of images in the linked sub folder is read out.

  As described above, since the content object for configuring the standby screen is basically downloaded by the push distribution method, the terminal 107 can maintain the latest standby screen. Even if the terminal 107 temporarily moves out of the service area, the standby screen can be displayed by the push type content object downloaded immediately before at the latest. In addition, if the terminal 107 temporarily moves out of the service area, the terminal 107 may download the latest push-type content object after returning to the service area by resending a short message or the like. Can do.

  In addition, since the management server 102 transmits the short message in a time zone in which the communication amount is small, it is possible to reduce the influence of other communications and calls due to the download of the push type content object.

  By the way, for example, a user who has the ability to create or edit a content object, or a user who obtains a content object through some route, displays the content object that has been created, edited or obtained as a standby screen, etc. You may want to customize the standby screen by using it. In such a case, such a content object is treated as a non-download type content object and stored in the content object folder 121. Some of these content objects are added to existing push-type content objects or pull-type content objects in response to additional content, but some of these content objects Some replace the push type content object or the pull type content object. For example, among such content objects, there is a weather forecast display script created by the user. A non-downloaded content object that replaces a push-type content object or a pull-type content object has the same identification information as the original content object, so it is automatically updated and downloaded as it is. It is overwritten by the content object. In order to prevent this, a special sub-folder is provided under the content object folder 121 as in the case where a sub-folder for each theme is provided, and the special sub-folder is excluded from the target of automatic update. You may make it store the content object which is not automatically updated by the special sub folder. Alternatively, a list of content objects included in the screen may be displayed so that the user can set permission / prohibition of automatic update for each content object. Based on the setting information, the push type content object download unit 125, the pull type content object download unit 133, and the browser 129 determine whether to download or cancel each content object. Further, the user may be allowed to set permission / prohibition of downloading for each content object stored in a special sub-folder.

[Content objects that make up the standby screen or function menu screen]
The content object constituting the standby screen includes an electronic document, CSS, an image (still image or moving image), sound, text, and script. These contents are stored in the content object folder 121.

  Each content object is basically a push type content object, but may be replaced with a non-download type content object. In addition to the push type content object, a pull type content object or a non-download type content object representing another content may be stored in the content object folder 121 as a content object constituting the standby screen. Good. In addition, the content object folder 121 is initially downloaded according to the push type distribution, but the next time and thereafter, the push / pull type content object downloaded according to the pull type distribution by a script or the like is a content object constituting the standby screen. May be stored.

  The push type content object is automatically downloaded at the initiative of the management server 102 first, and even when updated by the push type content object server 101, it is automatically downloaded at the initiative of the management server 102.

  The push / pull type content object is downloaded only at the beginning by the management server 102, and from the next time onward, it is downloaded from the pull type content object server 105 by the browser 129 according to the script.

  In the electronic document, the position of the content object stored in the content object folder 121 in the content object folder 121 is described, but the download destination is not described. This applies not only to pull type content objects, but also to pull type content objects. Accordingly, the pull-type content object stored in the content object folder 121 is acquired by the pull-type content object download unit 133 that knows the download destination or the browser 129 that executes the script including the designation of the download destination. Downloaded.

  Since the non-download type content object replaced from the push type content object has the same identification information as the push type content object, the push type content object server 101 is automatically led by the management server 102 as it is. It will be updated to the push type content object. In order to prevent this, as described above, the non-download type content object is stored in the sub-folder where automatic update is prohibited, and the information for prohibiting automatic update is held by the terminal for each content object. The push type content object download unit 125 refers to this.

  The added non-downloading type content object (non-downloading type content object that is not grasped by the management server 102) is a content object that is automatically downloaded without taking any measures for prohibiting the download. Will never be updated.

  The types of content objects constituting the function menu screen and the processing for the content objects are the same as in the case of the content objects constituting the standby screen, and thus description thereof is omitted.

[Content objects that make up the WEB menu screen]
The content object constituting the WEB menu screen includes an electronic document, CSS, an image (still image or moving image), sound, text, and script. All of these contents may be stored in the content object folder 121. In this case, the location of the content object is described by the identification information of the content object folder 121 and the identification information of the content object in the electronic document constituting the framework of the WEB menu screen. In particular, in the case of a push type content object stored in the content object folder 121, it is a download target according to push type distribution led by the management server 102.

  However, among the content objects that make up the WEB menu screen, the content object that may not be downloaded when the terminal is outside the service area is a push-type content object stored in the content object folder 121. Instead, it may be downloaded each time display of a WEB menu screen is required. Further, instead of being downloaded each time the display of the WEB menu screen is requested, it may be temporarily stored in the cache memory 131 and appropriately updated by the update method described above. The location of such a content object is described by a URL including the server domain name of the pull-type content object server 105 in the electronic document constituting the framework of the WEB menu screen. Further, the electronic document itself constituting the framework of the WEB menu screen may be a pull type content object. In this case, the electronic document is a URL including the server domain name of the pull type content object server 105. Describes the location.

  However, among the content objects that constitute the WEB menu screen, even if the content object does not need to be downloaded when the terminal is out of the service area, the large-capacity content object is stored in the content object folder. A push type content object stored in 121 is preferable. In this way, a large-capacity content object is stored in the content object folder 121 before the display of the WEB menu screen is requested, and when the display of the WEB menu screen is requested, the content object is immediately displayed. The WEB menu screen can be displayed based on the above. Such a content object is described by the identification information of the content object folder 121 and the identification information of the content object in the electronic document constituting the framework of the WEB menu screen.

  Note that all the above-described methods performed by the respective units shown in FIG. 1 can also be realized by causing a computer to read and execute a program for causing a computer to execute such a method.
